Aletters Patent 4No. 98,681, dated January 1.1, 187,0.

IMPRovED RAiLWAYcAR-AXLE coUPLING.

The Schedule referred to in these Letters Patent and making part 0f the same.

To all whom. fit may concern Be it known that I, Darn) F. FETTER, M.D., of the city, county, and State ot' N ew York, have invented a new and improved Coupling for Car-Axles, Sac.; and I do hereby declare that the following is st full, clear, and exact description thereof, which will enable others skilled in the art to malte and use the same, reference beinghadl to the accompanying drawings, forming part of this specification.

rl.`his invention relates to a new device for connectconnection will be perfect, andthat, still,.iudependent motion will be allowed to each ofthe parts.

'lhe invention consists in the employment of collars on the two parts of the axle, and ol' a ring and plates for lockingthe salire together, all as hereinafter more fully described.

,In the accompanying drawings Figure 1 represents a vertical longitudinal :section of my improved coupling.

Figure 2 is an cnd or face view of the same'.

Similar letters ot' .reference indicate corresponding parts.

.A B are the two parts of the axle to'be connected.

vUpon their contiguous endsare respectively mounted the collars C D, which are held in place by screws a, or equivalent means. l

The collar C on the axle A is provided with a groov'e, l), near Aits inner end, and is, between that groove and the inner end, made oi' conical form, i. e., gradually enlarged to have an oblique surface, c, as shown.

The collar D oi B has at its inner end a projecting flange, d, which extends beyond tbe collar C, as shown.

E is an annular iplate, with bevelletl inner edge e, fitted against that portion of the face of the ange l `which projects beyond the collar C, the bevelled edge `ot' the pla-te E being parallel with and close to the corresponding bevelled part c of the collar.

lUpon the face of the ring E is fitted au annular plate, F, which consists of two or more pieces, that are applied from' the sides to enter and lilll the groove b. y

Bolts f f secure the ring E and plate .F.irmly to the ilange of the collar D.

It is evident that the hevelled edge c, and the upward sides of the grooveb, eectually prevent a longtudinal displacement of the two shatts, as the ring and plate cannot play beyond the same, and that, nevertheless, perfect freedom is allowed tn each axle to yrevolve independent of the other.

Having thus described my invention,

I claim as new, and desire to secure by Letters Patent- The collar,C, baving the conical part c and groove b, in combina-tion with the ring E, sectional plate F, and'collar D,- all combined to serve as coupling for car-axles, Ste., as specified.
